For those who want to filter their drinking water, there are two popular choices, the under sink water filter and the faucet filter. The faucet type sits right on the end of your tap, filtering water as it comes out. The under sink type attaches to the plumbing under your sink, filtering the water before it gets to the tap.

But which one is best?

If you want the best filtration, the you’ll probably want to go for the under sink water filtration system. These systems will filter out more harmful substances like volatile organic chemicals and metals that either the tap filter or the pitcher type filter are relatively ineffective against.

The under sink water filters can be likened to the countertop systems but they are designed to sit under the sink. For the most part, they do the same job, but the under sink ones are hidden from view. Some people prefer not to look at a big water filtration gizmo on the counter, however you do lose storage space under your sink if you go this route.

One nice thing about these filters is that you can often get ones that filter the specific contaminants that your water supply might be abundant in. Some municipal or well waters might be really high in lime, arsenic, or nitrates and you can get filters that specialize in filtering these contaminants.

There are different types of under sink filtration systems, and you’ll want to do your research to find out which type is best for you. The two most common are reverse osmosis and distillation. These types of filters have two problems – they are slow and may not produce enough water and, along with the contaminants, they filter out important minerals.

If you want the best type of filtration, get a filter that uses two steps – one to get out the “bigger” stuff like sediment and chlorine, and another that filters out those pesky toxic chemicals.

When shopping for an under sink water filter, take cost and size into consideration, but the most important thing is to read the data sheet provided with the model. This will tell you what contaminants it filters and how much of them it will filter out. Make your decision based on the best water quality you can get for what you can afford.
